UNITED STATES PATENT JOSEPH J. PUKEL, OF SPRINGFIELD, MASSACHUSETTS, ASSIGNOR OF ONE-HALF TO ALFRED M. MORISI, OF SPRINGFIELD, MASSACHUSETTS.

WINDOW v FASTENER.

' Application filed. December 9, 1925. Serial No. 74,305.

My invention relates to improvements in devices for fastening windows, either when closed or partially opened, and Consists essentially of a peculiarly constructed keeper plate or strip adapted to be attached to one of the side rails of an upper Window sash, and a peculiarly constructed housing adapted to be attached to the top of the lower window sash associated with said upper sash, and provided with a spring-pressed bolt adapted to engage and release said strip, together with such other parts and members as may be necessary or desirable in order to render said device complete and serviceable in every respect, all as hereinafter set forth.

The primary object of my invention is to produce a very simple and inexpensive fastener for windows, which can be easily and quickly applied to the two sashes of practically any pair of slidingly cooperating windows, and wherewith such windows can be readily locked in closed position or when either is partially open. This fastener, with the exception of the bolt and spring, can be constructed of sheet-metal, and when so constructed is not only comparatively inexpensive to manufacture, but light in weight, compact, and sufficiently strong and durable for all ordinary purposes.

Another object is to provide a fastener, of the character described above, which is inter changeable, that is to say, which can be attached to the windows at either side.

A further object is to provide the lock stripof the fastener with handles to facilitate raising and lowering the upper window.

' Other objects and advantages will appear in the course of the following description.

I attain the objects and secure the advantages of my invention by the means illustrated in the accompanying drawings, in which Figure 1 is a front elevation of fragmentary portions of a window frame and a pair of upper and lower windows equipped with a fastener which embodies a'practical form of my invention, the lower window being show partly raised and secured or locked by means of said fastener; Fig. 2, an enlarged, perspective view of the keeper strip of said fastener; Fig. 3, an enlarged, front "elevation of the upper portion of said strip; Fig. 4, a transverse, vertical section through said strip, taken on lines H, looking in the direction longitudinal section through said housing,

on lines 6-6, looking in the direction of the associated arrow, Fig. 5.

In the first view are shown fragmentary portions of the parts and members at the.

left-hand side of a window, as follows: A vertical portion of the frame or casing at 1, the upper rail at 2 and a side rail at 3' of the lower sash, and the lower rail at 5 and a side rail at 7 of the upper sash. The fastener comprises a keeper strip 8 which is adapted to be attached to the upper sash rail 7, and equally well adapted to be attached to the other side rail of the same sash; and a housing 9 adapted to be attached to the tops of the lower sash rails 2 and 3 in front of said strip, or in front of the vertical plane 111 which the face of saidstrip is located, according to the relative positions of the windows. The housing 9 may, of course, be attached to the top of the lower window sash at the right-hand, as well as at the lefthand, side of said sash.

The strip 8 has therein a plurality of openings 10 to receive a corresponding number of screws or nails 11, by means of which latter said strip is fastened to the inside face of the rail 7 being secured thereto with the lower end of said strip a little above the rail 5. This strip is of sufficient width'to extend beyond inwardly the inner, beaded portion of the rail 7, and is formed with a longitudinal channel 12 therein, and a longitudinal lip or flange 13 thereon. The channeled portion of the strip 8 extends rearwardlytoward the aforesaid beaded portion of the rail 7, as does also thejlip 13, the latter being at right-angles to the main portion of said strip. In what may be termed the bottom of the channel 12 is a plurality of bolt-receiving openings 14, said openings preferably being elongated on their horizontal centers, for the reason presently to be explained. The lip 13 at the top and bottom is separated from the rest of the strip 8, and bent outwardly and respectively upwardly and downwardly, to form two hooks which serve as handles 15. The housing 9 consists of a flat plate -recessed inthe center at the front end, as represented at 16, and having at said end a pair of downwardlyextending lugs 17, and a barrel 18 on said plate in the longitudinal center thereof, back of the recess. There is an opening 19 in the housing plate on each side of the barrel 18, and a similar opening in each lug 17, or four such openings in all in the present example, to receive a corresponding number of screws or nails 20 by means of which the housing 9 is secured to the lower window sash, two of said nails passing downwardly and two rearwardly into the rails below and behind, respectively. in this manner and by this means the housing is secured to its sash.

The front end of the barrel 18 is closed, as shown at 21, and perforated to receive a lock bolt 22. The bolt 22 passes through the front end 21 intothe barrel 18, and is of sullicient length to extend beyond the rear end of said barrel and into any one of the openings 14: in the strip 8. This bolt consists merely of a rod bent at its forward terminal to form a handle 23. Passing laterally through the bolt 22 and extending beyond opposite sides thereof, at a point considerably removed from the handle 23, is a pin 24:, and a spiral-spring 25 encircles said bolt between said pin and the front end 21 of the barrel. The spring 25 tends constantly to urge the bolt 22 rearwardly.

Upon grasping the handle 23 and drawing the bolt 22 forwardly, against the resiliency of the spring 25, until said handle is in front of the vertical plane of the lugs 17, andthen partially rotating said bolt to locate said handle in front of one or the other of said lugs, the bolt, when the handie is released, is retained by the latter in retracted position and out of locking engagement with the strip 8see Fig. 5. When the bolt 22 is partially rotated by the handle to carry the latter upwardly above the top plane of the lower sash and the top plane of the housing plate, and released, the spring 253 immediately acts to impel said bolt rearwardly into locking position. While in locking position the bolt may enter any opening 14:.

i In practice, assuming that the strip 8 and the housing 9 have been secured to the upper and lower sashes, respectively, in the manner hereinbefore described, the operation of the fastener is briefly described as follows:

When the windows are both closed,,and the handle 23 is turned upwardly into the approximate position shown in Figs. 1 and 6, or to an extent which enables the same to clear the parts of the housing 9 separated by the recess 16, the rear end of the bolt 22 enters the lowermost opening 14, and thus prevents the windows from being opened. To unfasten the windows, draw the bolt 22, by means of the handle 23, forwardly to release the channeled part of the strip 8, and turn said handle downwardly in either direction until it engages one or the other of the lugs 17, or that part of the lower window sash which extends across behind the space between said lugs. Preferably the bolt is turned far enough to en able the handle 23 to engage one of the lugs 17, and thus avoid marring the sash. The windows are now free to be moved up and down. If it. be desired to lock the windows while one is open, the bolt 22 is partially rotated to release it to the spring 25, when said spring forces said bolt rearwardly, can rying the rear end of the bolt into the channel 12, and such end enters the first opening 14 that registers therewith or with which the bolt end registers, accordingly as the upper window is moved down or the lower window is moved up. again unlocked in a similar manner as before. The maximum extent to which either window can be opened and secured by this fastener is determined by the distance apart of the uppermost and lowermost openings 1+. in the strip 8.

There may be more or less play from side to side of the windows, and it is for the purpose of accommodating the openings 14; to the bolt 22, in such event, that said openings are made elongated.

The handles 15 afford convenient means for raising and lowering the upper window, the forefinger and hand being placed beneath the upper handle to raise the window, and the forefinger being hooked over the lower handle to lower said window.

The channel 12 affords an efficient guide for the bolt 22 to direct the same to the openings 14, when said bolt is in advanced position and one or the other of the. windows is moved up or down.

It is not necessary, of course, to fasten the bolt in retracted position while raising or lowering either window, since said bolt may be held in such position with the finger and thumb.

The Walls of the barrel 18 may taper so that said barrel will be smaller at the rear The windows are than at the front end, and thus afiord at the rear end support for the corresponding end of the bolt 22 of a character to prevent the same from having any appreciable lateral play, or excessive amount of free vertical movement. At the front end the bolt is well supported in the end member 21.

More or; less change in the shape, size, construction, and arrangement of some or all of the parts of this fastener may be made, without departing from the spirit of my invention or exceeding the scope of what is claimed.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a window fastener, a keeper strip adapted to be secured to a side rail of a window sash, and having a lip arranged. approximately at right-angles to the main portion of said strip, terminally separated from the latter, and bent into handle formation.
